Two year old thread is two years old

And growing conditions wouldn't really be affecting the pattern of leaf growth, it might affect the color and size of the leaf itself but not the placement of the leafs

Could growing conditions affect leaf structure??

Oh. Make sense. Without looking at leaf structure, it'll be very hard to tell the diff between rubin and repen.

Nope. 'Rubin' has leaves that are opposite, sub-opposite or alternate. L. repens has leaves that are always opposite. The former is probably a hybrid between something like repens and an alternate-leaved plant.

I thought that Ludwigia sp. 'Red' was decided to be a red variety of L. paulustris. Making it Ludwigia paulustris 'Red'. I think it was Chad to was telling me this.

It is very similar in shape so is entirely believeable
palustris seems a bit mroe elongated in leaf form.
i woulnd't mind setting up a comparison grown under the same conditions if i could get my hands on some

very small leaves, definitely a sign of no co2.. ludwigia repens leaves are about the size of a quarter when receiving all required nutrients

Thank you very much, it grows great but what you have said about the leaves being quarter size with co2 makes sense because I see this plant growing by canals (that is where I got it) and the leaves on those are quarter size while mine are nickel size if even that.

I just assumed since it grew so fast that water changes were enough.

I have a second corckscrew val tank recently set up and was thinking of DIY CO2 , will try it in both tanks.

The water here is the best for no algae at all and amazing plant growth but as you know doesn't come with CO2 so going to try it with soda bottle and air stone in tank.

while on the topic, I feel like sp. atlantis should also be discussed with these two
sure, price wise there is a big difference now, but appearance wise and size wise and all I think these three sp. are very similar.
